Bed Lighting

buy at Nilightinstall
15-30 min
pairs with: Tonneau covers/bed liners and other 12V plug-in accessories (backup cameras, trailer wiring)
number source
Two 60 inch light strips that stick under the rails of your truck bed so you can see what you are doing after dark. The kit comes with the on/off switch, a blade fuse, and a splitter so both strips run off one wire. Universal fit, meaning it is not cut for one truck, it works in any bed.
why this one: Cheapest thing on this list that solves a real problem. A lot of bed light kits leave out the switch or the fuse and you end up buying parts twice. This one has both.

30-45 min
pairs with: Tonneau covers and bed mats/liners; cargo tie-downs/nets for loading and unloading in low light
number source
Same idea as the two strip kit with a third strip added. On a long bed, two strips leave a dark spot in the middle and the third strip fills it. Universal fit, it is not cut for one truck.
why this one: Buy this one instead of the two strip kit if you have a long bed. About eight dollars more for the extra light.
Bed Protection
$42.99
buy at Walmartinstall
~15-20 min (trim + drill-mount hardware)
pairs with: Floor Mats, Bed Lighting
requires: trimming to fit. BDK ships this mat at 60 by 19.5 inches as a universal trim-to-fit design, so on a midsize tailgate it needs cutting down with scissors before it will sit right. Mounting hardware is included and fitting it involves drilling.
number source
A thick rubber mat that covers the inside face of your tailgate. That is the surface that actually gets scratched when you slide things in and out of the bed. Universal, so you trim it with scissors and screw it down.
why this one: The only bed protection product we found under fifty dollars. A real full length bed mat starts around $115 because it is one big molded piece cut to a specific bed length. This one protects the part that takes the most abuse.
$75.99
buy at AutoZoneinstall
~20-30 min (trim + drill-mount hardware)
pairs with: Floor Mats, Bed Lighting
requires: trimming to fit, and a bare metal tailgate. Cat ships this mat at 62 by 21 inches with cut guides marked at 17x54, 19x59, 20x60 and 21x62 inches, so it covers full-size and midsize gates but nearly always needs cutting with scissors or a utility knife. Cat states it is made for bare metal tailgates and is not compatible with plastic tailgates. Mounting hardware is included and fitting it involves drilling.
number source
A thicker, tougher version of the basic tailgate mat. It covers the inside face of the tailgate so loading and unloading does not chew up the paint. Universal, trim it to fit.
why this one: Heavier duty than the cheap mat and a brand name people recognize, which helps it sell. AutoZone runs about sixteen dollars over Amazon, so the comparison favors us.

NOT Compatible for 2019-down Silverado/Sierra 1500 Old Body Style or 2007 Classic." Warns it "may interfere with front-end sensors." All mounting hardware included, no drilling.
number source
A steel bull bar for the front of 2019-2024 Silverado and Sierra 1500 trucks with the newer body, including a 17 inch LED light bar and a removable skid plate. No drilling required.
why this one: Guard and light bar together for 179.99. The 2019 model year is where people get these wrong, because GM sold two different bodies that year. This one fits the new body only. If yours is a 2019 LTD or Classic, you need the other version. Nilight warns it may block front end sensors.

number source
A steel bull bar for the front of 2007-2018 Silverado and Sierra 1500 trucks, with a 17 inch LED light bar and a removable skid plate. All mounting hardware is included and no drilling is needed.
why this one: Guard and light bar together for 179.99. This is also the one that sorts out the confusing 2019 model year, because it fits the 2019 Silverado 1500 LD and Sierra 1500 Limited, which are the older body carried over for one more year. It does not fit the 2019 and newer body, or the 2007 Classic. Nilight warns it may block front end sensors.

1-2 hrs
pairs with: Headers, Tune
number source
A cat-back exhaust replaces the factory pipes, muffler and tips behind the catalytic converter. This is aFe's Vulcan Series system, built from 3-inch stainless tubing with polished tips.
why this one: aFe claims the smallest gain of any cat-back here, +5 hp and +6 lb-ft, so at $1,153 you are paying mostly for sound and stainless construction. One ordering trap: aFe also sells an older MACH Force-Xp cat-back that fits the 2019 Silverado 1500 LD carryover body, which is a different truck, so buy by this Vulcan part number. A black-tip version of the same system exists if polished is not your look.

install
1-2 hrs
pairs with: Headers, Tune
number source
A cat-back exhaust replaces everything behind the catalytic converter - pipes, muffler and tips - with less restrictive tubing. This is AWE's 0FG system in the split rear-exit layout, so both tailpipes exit behind the rear wheels through the factory bumper cutouts with OE-style tips.
why this one: This is the priciest cat-back in the group at $1,445 and AWE publishes no horsepower number for it, so you are buying fit, finish and a factory-look tip rather than a power figure. AWE sells the same 0FG system under several tip and exit styles from roughly $1,295 to $1,895, so make sure this OE-style version is the look you actually want before you order.

A cat-back exhaust replaces the piping and muffler from the catalytic converter back; this is Borla's S-Type system with dual rear-exit carbon fiber tips for the 5.3L V8.
why this one: Borla's aggressive S-Type tone with a premium carbon fiber tip finish - a step up in looks from the standard chrome-tip S-Type.

~1-2 hrs
pairs with: Headers, Intake, Tune
number source
A cat-back exhaust system replaces everything from the catalytic converter back - resonator, muffler, and tailpipes - while leaving the factory manifolds and catalytic converters in place. It is a bolt-on install that mainly changes exhaust sound with a modest, real airflow gain.
why this one: This is Borla's dedicated 6.2L-specific S-Type system (not a shared 5.3L/6.2L part), confirmed on Borla's own site for both 2014-2018 Chevrolet Silverado 1500 and GMC Sierra 1500. Note it is only listed for Extended Cab/Standard Bed and Crew Cab/Short Bed configurations - other cab/bed combos are not confirmed on this SKU.

number source
A cat-back exhaust replaces the piping and muffler from the catalytic converter back; this is Corsa's Sport 3.0in dual rear-exit system with factory-style bezels for the 5.3L V8, 147in wheelbase trucks.
why this one: Corsa backs this one with a real dyno claim (+17 hp / +15 lb-ft) rather than just a sound upgrade, and keeps the factory-look bezels instead of aftermarket tips.

number source
A cat-back exhaust system replaces everything from the catalytic converter back - resonator, muffler, and tailpipes - while leaving the factory manifolds and catalytic converters in place. It is a bolt-on install that mainly changes exhaust sound with a modest, real airflow gain.
why this one: Corsa's own site states a specific, real claimed gain (+17 hp/+16 lb-ft) for this exact 6.2L Silverado/Sierra system rather than a vague "improves flow" pitch, and it is sold direct through Corsa's approved affiliate program (Corsa Direct) so a purchase here can actually be tracked.

pairs with: Headers, Tune
number source
A cat-back exhaust swaps the factory pipes, muffler and tips behind the catalytic converter for less restrictive tubing. This is Flowmaster's FlowFX system in a dual rear-exit layout, with both tailpipes exiting behind the rear wheels.
why this one: Cheapest cat-back here at $949.95 and the only one claiming a double-digit gain at both ends, +21 hp and +26 lb-ft. That figure is Flowmaster's own published number rather than an independent test, and it was found on a reseller listing instead of Flowmaster's page, so read it as a best case and not what your truck will make.

number source
A cat-back exhaust replaces the factory pipes, muffler and tips from the catalytic converter back. This is Gibson's Dual Extreme system in stainless steel, covering 2019-2025 5.3L trucks.
why this one: Gibson is the only one here that tells you where its claimed gains land: +10-15 hp and +15-20 lb-ft, optimized for 1,800-3,000 RPM, which is the range you tow and pull away from a light in. It is still a manufacturer claim rather than an independent dyno, and the $1,044 price was a sale off a $1,743 list, so confirm current pricing before you count on it.

A cat-back exhaust system replaces everything from the catalytic converter back - resonator, muffler, and tailpipes - while leaving the factory manifolds and catalytic converters in place. It is a bolt-on install that mainly changes exhaust sound with a modest, real airflow gain.
why this one: This is MagnaFlow's off-road-oriented "Overland" cat-back with a high-clearance design, confirmed by MagnaFlow as one continuous SKU across the full 2019-2026 span including the 2022.5 refresh - no separate pre/post-refresh part needed.

why this one: MagnaFlow's own listing confirms this SKU for both the Chevy Silverado 6.2L and GMC Sierra 6.2L in one part, with a single passenger-side rear exit and polished stainless tips - a factory-looking upgrade rather than a loud aftermarket look.

Replaces the factory plastic turbo-to-intercooler (hot side) and intercooler-to-throttle-body (cold side) tubes with mandrel-bent aluminum piping and factory-style quick-connect fittings, smoothing out the OE tubing's restrictive bends.
why this one: The only branded charge-pipe kit currently sold for this specific engine platform (GM 2.7L Turbo L3B/TurboMax) - the factory plastic tubing has tight bends that are a known restriction point under boost; this is a straightforward bolt-on with no ECU flash required.

Replaces the factory plastic resonator on the charge-air path between the turbo compressor outlet and the intercooler inlet with a straight aluminum pipe, removing a flow restriction and the muffling effect that quiets turbo/compressor noise.
why this one: The cheapest real bolt-on for this engine's charge-air path and explicitly confirmed to cover the 2022+ TurboMax/High-Output revision as well as the 2019-2021 first-gen engine - a good standalone starting mod or a complement to the aFe charge pipe kit.

pairs with: Phone/GPS dash mounts, and other diagnostics/maintenance tools like tire-pressure or battery testers
number source
A handheld tool that plugs into the port under your dash and tells you why the check engine light came on. It shows a code, explains what the code means on its own screen, and can turn the light off. No batteries and no phone needed. Works on any 1996 or newer vehicle, which is what OBD2 means.
why this one: 66,000 reviews and it does the one job most people need. Amazon runs about ten dollars under the manufacturer here, which makes the price comparison on the page honest and useful.

number source
A small plug that goes into the port under your dash and sends the information to your phone over Bluetooth. You read the codes in a free app instead of on a screen. This is the advanced version, which answers more commands for people who like to dig into the data. Works with both iPhone and Android.
why this one: The plus model is the one that works on iPhone as well as Android, so nobody ends up with something that will not talk to their phone.

Same idea as the plus model for less money. It plugs into the port under your dash and sends codes to a free app on your phone over Bluetooth. Works with both iPhone and Android.
why this one: More than twice the reviews of the plus model and ten dollars cheaper. This is the default pick for the code reader slot unless someone wants the extra commands.

Molded rubber trays for the two front footwells with a raised lip all the way around. Mud, snow and spilled drinks stay in the tray instead of soaking into the carpet. Pull them out and hose them off. They are cut for this truck, so they lay flat and do not slide around.
why this one: GM version of the F-150 liner, and the years match the Silverado and Sierra guide.

A four piece set of deep rubber mats with tall edges that hold water and mud instead of letting it run onto the carpet. Universal fit, which means they are not cut for one truck, you trim them with scissors so they sit right in your footwells.
why this one: 121,000 reviews, the most of anything on this list. At this price it is the version of a floor liner people buy on impulse, and AutoZone runs about fifteen dollars over Amazon so the comparison favors us.

Replaces the stock fog lights with Baja Designs Squadron LED pods that mount in the factory fog light pocket using the factory mounting points. The kit includes wire adapters that plug straight into the OEM connector, so there is no cutting or soldering - it keeps your factory fog light switch working.
why this one: A step up from the Diode Dynamics kit in raw output on paper (2,420 measured lumens per light vs Diode Dynamics Pro at 3,000 - actually slightly lower on this one metric, but Baja publishes peak candela at 15,800 which is a different measurement, so the two are not directly comparable spec-for-spec). Pick this one for the Baja Designs brand and its aspheric projector optics with a sharp SAE cutoff if that matters more to you than saving the roughly $26 the Diode Dynamics kit costs.

number source
Swaps your stock fog lights for two 3-inch LED pods that bolt straight into the same holes your factory fog lights use. The kit ships with a bracket and a plug-in adapter already sized for this truck, so there is no cutting wires or drilling new holes - it only bolts on if your truck already came with fog lights from the factory.
why this one: Diode Dynamics sells this same pod in three brightness levels: Sport, Pro, and Max. Pro is the middle tier, noticeably brighter than the base Sport version (3,000 measured lumens vs 1,520) without the roughly $200 jump to Max. Good pick if you actually drive dark backroads at night; go with Sport if fog lights are mostly cosmetic, or step up to Max if you want the most light and do not mind the price.

manufacturer claim

2-3 hrs
pairs with: Tune, Supercharger
number source
This is a flex fuel conversion kit. It adds an ethanol content sensor to the fuel line and a controller that plugs into the factory harness, so the truck reads how much ethanol is in the tank and adjusts fueling on its own. That lets you run E85, gasoline, or any mix of the two.
why this one: No tune, no injector swap and no pump swap, and the module stays invisible to scan tools, so this is the simplest way onto E85. The retailer listing for this part claims 40 to 45 wheel horsepower on E85. The catch is obvious: you get nothing out of it unless E85 is actually sold where you live.

A flex-fuel system adds a sensor and controller that let the factory ECU safely recognize and adapt to ethanol-blended fuel (like E85) instead of just gasoline, without needing a full standalone tune.
why this one: AFD builds this specifically for the 6.2L (2020+ T1XX), explicitly plug-and-play with "no tuning required," confirmed for both GMC Sierra and Chevrolet Silverado in the product title itself.

Running E85 can affect powertrain warranty and requires E85-compatible fuel-system components downstream; check before relying on this for daily E85 use.

A flex-fuel system adds a sensor and controller that let the factory ECU safely recognize and adapt to ethanol-blended fuel (like E85) instead of just gasoline.
why this one: This shared 5.3L/6.2L SKU works for either engine on the 2014-2018 truck, both makes confirmed by name in the product title. FITMENT AMBIGUITY FLAGGED: AFD's own page states fitment as "2014-19" without breaking it out by engine or by trim; since the 6.2L engine was never offered on the 2019 Silverado 1500 LD / Sierra Limited K2XX carryover (per this catalog's own vehicles table, that trim is 5.3L L83-only), the "19" portion of AFD's stated range is treated here as unverified for the 6.2L specifically and this row is scoped conservatively to 2014-2018 only.

supports added power

8+ hrs / shop recommended
pairs with: Tune, Supercharger
number source
A set of eight direct injection fuel injectors that flow about 71 percent more than the factory units. Like any injector upgrade they add fuel capacity rather than power, so they are there to feed an engine that has already been built or boosted.
why this one: This is the bigger of Katech's two sets, rated to 1,400 wheel horsepower on gasoline or 1,000 on E85 for $700 more than the Stage I. That headroom is real, but most street trucks will never reach even the Stage I ceiling, so only buy up if your power target genuinely demands it. Same 7.5mm stem, so 2021 and newer heads are out, and a supporting tune is required either way.

8+ hrs / shop recommended

number source
A set of eight direct injection fuel injectors that replace the factory ones and flow about 45 percent more than stock. They do not make power on their own. They give the fuel system enough capacity to feed an engine that is already making more power than stock.
why this one: Katech rates this set to support up to 1,200 wheel horsepower on gasoline or 900 on E85, which covers most boosted 5.3L and 6.2L builds without stepping up to the Stage II set. It only makes sense alongside a supercharger or a built engine plus a supporting tune, and it is a deep teardown job on a Gen V engine. The 7.5mm stems will not fit 2021 and newer heads.

pairs with: Cat-Back, Tune
number source
Headers replace the cast-iron exhaust manifolds bolted to the cylinder heads with smooth tubular pipes, so exhaust leaves the engine more freely. This is American Racing Headers' full long-tube system in 304 stainless with 1-3/4 inch primary tubes, a 3-inch merge collector and a catted Y-pipe, so the catalytic converters stay in the system.
why this one: ARH sells this same long system in two tube sizes at nearly the same price, and this is the smaller 1-3/4 inch version. ARH publishes no horsepower figure for either, and a long-tube swap is an 8-plus hour job most people hand to a shop and follow with a tune. One caveat before ordering: Sierra 1500 fitment was not confirmed for this specific part number.

These are American Racing Headers' long tubes in 304 stainless with 1-7/8 inch primaries, a 3-inch collector and a 200-cell catted Y-pipe, so the catalytic converters stay in place.
why this one: This is the larger-tube version of ARH's long system and it costs about $35 more than the 1-3/4 inch kit, which makes tube size the real decision rather than price. Unlike its smaller sibling, this part number is confirmed to fit the 5.3L Sierra 1500 as well as the Silverado. ARH publishes no power number, and this is a shop-level install that wants a tune afterward.
heads up
Same ARH disclaimer as 1-3/4in version: catted but marketed "For Racing Purposes Only," off-road use per Clean Air Act language on ARH's own site.

Long tube headers replace the factory exhaust manifolds with true tuned header tubes plus a catted connection pipe - the biggest single airflow upgrade available for this engine, but a harder install than a cat-back or intake.
why this one: American Racing Headers builds this specifically for the 6.2L T1XX truck (2019-2026), not a shared 5.3L/6.2L part, and keeps the catalytic converters in the Y-pipe so it stays closer to street-legal than an off-road-only header.

Long tube headers replace the factory exhaust manifolds with true tuned header tubes plus a catted connection pipe - the biggest single airflow upgrade available for this engine, but a harder install than a cat-back or intake.
why this one: This is ARH's dedicated K2XX-era 6.2L header (2014-2018 only), separate from their 2019+ T1XX part, with a catted Y-pipe. GMC Sierra fitment is not confirmed on this specific listing, so treat it as Chevrolet-Silverado-verified only for now.

Headers replace the cast-iron exhaust manifolds with tubular pipes. These are shorty headers, meaning they stay about the size of the stock manifolds and bolt back to the factory Y-pipe, built by BBK with 1-3/4 inch mandrel-bent tubing and a titanium ceramic coating.
why this one: At $569.99 this is by far the cheapest way into headers on this truck, and because shorties reuse the factory Y-pipe the install is shorter than a long-tube system, though still a 5 to 7 hour job. BBK's "up to 14 hp" is marketing copy with no dyno chart behind it. Retailers also disagree on whether coverage ends in 2022, 2023 or 2024, so check your year before ordering.

No CARB-legal or off-road-only statement found on any retailer page checked; treat as unconfirmed emissions status (shorty, uncatted header design typically sold off-road-only, but no explicit statement located).

Headers replace the cast-iron exhaust manifolds with tubular pipes. This is Kooks' full long-tube kit: 1-7/8 inch T304 stainless primaries plus a 3-inch OEM-style catted Y-pipe, so the catalytic converters stay in the system.
why this one: At $3,776 this is the most expensive part in this group and Kooks publishes no power figure for it, so it is a buy-the-brand decision. Budget for a shop, 8-plus hours and a tune on top of the part price. Retailers also disagree on the end year, AmericanTrucks saying through 2026 and Beefcake saying 2024 while Kooks lists only "2019+", so confirm your model year first.
heads up
Not CARB-legal per Beefcake Racing's checkout note; no CARB EO number found on any page checked.

Headers replace the cast-iron exhaust manifolds with tubular pipes. These are Kooks' shorty headers, which bolt back to the factory Y-pipe, built with stepped primaries that start at 1-5/8 inch and open up to 1-3/4 inch.
why this one: This costs nearly three times BBK's shorty for the same install job, so you are paying for Kooks' construction and its stepped Torque Series design, which Kooks says is built for power across the RPM band rather than just up top. No horsepower number is published. Worth knowing: Kooks' own fitment text names the Silverado and not the Sierra, though a verified review on their page is from a 2026 Sierra AT4 owner.
heads up
General California Prop 65 / catalytic-converter-tampering warning present; no explicit CARB-legal or off-road-only statement found; connects directly to OEM catalytic converters (uncatted header itself).

Long tube headers replace the factory exhaust manifolds with true tuned header tubes plus a catted connection pipe - the biggest single airflow upgrade available for this engine, but a harder install than a cat-back or intake.
why this one: Kooks' own page confirms this exact header fits continuously from 2014 through 2026, spanning both the K2XX and T1XX chassis generations without a separate part - useful if you are not sure which chassis generation your specific truck is.
